Write these values as a full decimal number (not using scientific notation) in standard si base units, without any prefixes, preserving the number of significant figures (a) m= 16.0 mg (b) x= 12.5 x 10^3 km

(a) The base unit of mass is grams. Every gram is consists of 1000 mg or milligram. To convert the given milligram to gram, we just have to divide the number by 1000. This will give us an answer of,
                                      0.016 grams

(b) The base unit of distance is meter (m). Every kilometer (km) is consist of 1000 m. To convert, we just have to multiply the given number by 1000. The answer to this item will be
                                        12,500,000 meters
